neutral position, turn screw counter-clockwise to reduce idle
speed, or clockwise to increase idle speed. Set idle speed high
enough to keep engine running smoothly, but not high enough to
engage the clutch.
Low Speed Needle: No adjustment recommended. For increased

Caution-never turn in more than 2 turns from flush. This will
cause engine to run too lean and will result in damage.
